It is nowadays part of the municipality of Stichtse Vecht.

Maarssenbroek is divided into thirteen residential areas with names picked from plant types and animal species as listed below.

The entrances to the residential areas are marked on the main access roads by blue signs on which a silhouette of the animal responsible for the area's name has been stenciled in white.

The streets in the residential areas of Maarssenbroek don't have names themselves; the addresses are composed by appending the house number to the area name.

Within the residential areas the location of the addresses are indicated with green signs in white lettering pointing out the street where a specific house number can be found (e.g. a sign "501-599" pointing to the right).
